Detailed Directions for Rating Part II of the Written Test

Note: Beginning in the 2012-2013 school year, teachers are no longer permitted to scoretheir own students’ responses.

This guide contains detailed directions and criteria for scoring student responses to the questions in Part II of the written test. Raters should become familiar with the detailed directions andscoring criteria before beginning to score the student responses. Refer to the 2013 Manual forAdministrators and Teachers for suggestions about organizing the rating process.

In rating the student responses, follow the procedure outlined below.

1. Familiarize yourself with the system your school is using for processing the answerpapers and recording the test scores.

2. Have a test booklet on hand. Read each Part II question carefully. Note exactly what isrequired.

3. Carefully read the criteria provided in this guide for scoring each question.

4. For most questions, examples of acceptable responses are provided. Acceptableresponses include, but are not limited to, the examples given. Other responses that convey the same general meaning as those given in this guide should also receive credit. Raters must use their judgment to decide if the student’s answer meets the criteria. You may find it helpful to discuss questionable student responses with otherraters.

5. Acceptable responses separated by a slash (/) are considered to be the same responseand should be counted for credit once.

6. Discuss with other raters the requirements of each question and the scoring criteria.When you are certain that you clearly understand the requirements and criteria, you areready to begin scoring the student responses.

7. It is recommended that you score all the student responses to one question before proceeding to the next question. This method helps ensure that the scoring criteria areapplied consistently.

8. Students should not lose credit for incorrect spelling, grammar, capitalization, or punctuation.

9. In responses to questions where a specific number of answers are required (e.g., identify three materials, give two examples), if the student provides more than therequired number of answers, score only the required number, in the order in which theyappear.

Int.-Lev. Sci. Rating Guide—June ’13 [2]

10. Record the number of credits you allow for each question in the table provided on theback cover of the test booklet. The maximum number of credits for each questionappears in the table.

11. When you have finished scoring all the Part II questions, add the credits allowed for eachquestion to obtain the total raw score for Part II.

12. Follow your school’s procedure for transferring Part II scores to the student’s scannableanswer sheet. These are local decisions that depend on the answer sheet your schooluses. Some schools will transfer a score for each Part II question while others may transfer a total raw score for Part II. Check to be certain that the student name on thetest booklet matches the name on the answer sheet.

Online Submission of Teacher Evaluations of the Test to the Department

Suggestions and feedback from teachers provide an important contribution to the test development process. The Department provides an online evaluation form for State assessments. It contains spaces for teachers to respond to several specific questions and to make suggestions. Instructions for completing the evaluation form are as follows:

1. Go to http://www.p12.nysed.gov/assessment/teacher/evaluation.html.

2. Select the test title.

3. Complete the required demographic fields.
